ROPE-DRIVEN SAWMILL SET-WORKS.

Specification of Letters Patent.

Application filed March 23, 1908.

Patented. June 1, 1909.

Serial No. 422,863.

To all whom it may concern:

Be it known that I, ULRICH ANDERSON, a citizen of the United States, residing at Fond du Lac, in the county of Fond du Lac and State of Wisconsin, have invented certain new and useful Improvements in Rope- Driven Sawmill Set-W'orks, of which the following is a specification.

My present invention pertains to improvements in rope-driven saw-mill set-works, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein:

Figure 1 is an elevation of the apparatus, looking toward the saw Fig. 2 a vertical sectional view, taken on the line aa of Fig. 9; Fig. 3 a similar view, taken on the line b-b of Fig. 1; Fig. 4 a top plan view of the apparatus, the setting arm being shown as moved around to a point where the motion of the set shaft will be arrested; Fig. 5 a top plan view of the clutch-drum; Fig. 6 a perspective view of the setting arm and its allied parts; Fig. 7 a detail sectional view showing the indicator and a portion of the upper face of the drum in combination with which it works; Fig. 8 a detail perspective view of the indicator, as viewed from the under face thereof Fig. 9 a top plan view of the apparatus, certain portions of the lower part thereof being omitted, and the parts being shown in their initial setting position; Fig. 10 a vertical sectional view of the upper portion of the setting mechanism; Fig. 11 a detail sectional view, illustrating the driving mechanism employed to impart a receding movement to the knees; Fig. 12 a similar view of the same parts; Fig. 13 a perspective view of the locking block employed to lock the setting lever to the clutchdrum; Fig. 14 a similar view of the block used to arrest the movement of the clutch-drum; Fig. 15 a detail perspective view of one of the links or levers employed in connection with the receding mechanism; Fig. 16 a horizontal sectional view, taken on the line cc of Fig. 2, illustrating the clutchdrum and the clutch members or shoes which work in conjunction with the inner face thereof Fig. 17 an enlarged detail sectional view of one of the clutch-shoes and its operating link; Fig. 18 a perspective view of one of the clutch-shoes as viewed from the under face thereof; Fig. 19 a vertical sectional View, taken on the line dd of Fig. 17 Fig.

20 a horizontal sectional view, taken 011 the line ee of Fig. showing the yoke or frame which works in connection with the arresting mechanism for the clutch-drum; and Fig. 21 a perspective view, looking toward the under face, of the quill and clutch-supporting plate.

The main object of the invention is to provide a simple and efficient mechanism to effect an accurate setting of the knees at predetermined distances and to so construct the mechanism that the movement of the knees will be instantly stopped when they have been moved to the desired extent.

A further object of the invention is to provide means whereby the strain will be taken off of the parts when the setting lever reaches a predetermined point in its travel, and to provide a positive stop for the setting mechanism, which will be automatically thrown into operation by the setting lever while at the same time the lever is disconnected from the driving or actuating mechanism.

Another object of the invention is to provide means whereby the locking block or set-arresting member may be thrown out of operative relation, along with the clutch mechanism, which causes a forward movement of the knees, when it is desired to throw the receding mechanism for the knees into operation.

A still further object of the invention is to provide a mechanism wherein any slipping of the clutches employed in the machine will not affect in the least the accuracy of the setting movement.

With these and other objects in View, a description of the machine in its preferred form will be given.

In the drawings, 1 denotes the base, which is mounted upon the carriage 2. Said base carries a frame or housing preferably composed of two parts, 3 and 4, secured together in any suitable manner, and provided with extensions, as shown in the drawings, for the reception of the gears.

The driving rope or cable 5 passes about the sheave-wheels 6 and '7, the latter being the driver, the sheaves rotating in the direction indicated by the arrows in Fig. 1.

Secured to the sheave 7 is a shaft 8, carrying at its inner end a bevel pinion 9 which meshes with a similar gear 10 mounted upon the lower end of a vertically-disposed shaft hub 24 of a pinion 25, the hub finding its bearing upon the upper end of the sleeve 17.

11. The lower end of said shaft 11 passes through a bushing 12; mounted in a bearing 13 formed as a part of 'the frame or housing, while the upper end of the shaft passes through a sleeve 14, which finds its bearing in a box or projection 15. A second vertically-disposed shaft 16 has a bearing at its its bearing in a brass sleeve or bushing 20' supported by a boX or housing 21',for1ned as an upward extension of the frameor housing. Secured to the'shalt 11 1s a pinion 22, Fig;

3, said pinion meshing with a gear 23 attached to the lower end of the DIO16GtlIlg Pinion 25 meshes with a gear 26 secured to thelower or extended end of the hub 27 of a pinion 28, the hub finding its bearing upon a sleeve 29 mounted upon the shaft 11. pinion 28 inturn meshes with'a gear 30 secured to the lower end of the quill 19. Thus it will be seen that so long as the rope or cable is in motion (as it is at all times in practice) a constant rotation will be'imparted to the quill 19, and through the mechanism hereinafter to be described, a step-bystep movement will be given to the shaft '16. To the lower end of said shaft is secured a bevel gear 31, which meshes with a bevel pinion 32 secured upon a set shaft 33, which passes through bearings formed in the lower portion of the frame or housing.

The upper end of the quill 19 has formedupon a curve which when the shoes are moved outwardly contact with the inner face of a drum 37, the hub 38 of the drum being keyed or otherwise secured to the upper end of the shaft 16. Adjustable links 39, shown in detail in Fig. 16, connect each of the radially-movable shoes 36 with a ver tically-inovable sleeve 40, the latter being mounted upon quill 19. As the sleeve or collar is raised, the clutch-shoes will be moved outwardly into contact with the inner face of the clutch-drum, and will impart a rotary motion to said drum, inasmuch as the quill 19 and its head 34 are constantly rotated. A collar 41 is formed upon the lower end of the sleeve and a two-part ring 42 is seated in the collar,the collar, however, being free to rotate within the ring. Trunnions 43 extend outwardly from the collar, and a yoke-shaped frame 44 is swiveled upon said trunnions and passes about the various The members, as best shown in Fig. 20. An eye 45 formed at one end of the yoke or=franre,* embraces a link 46 towhich it is pivotally connected. The lower end of the link has pivoted thereto a short link 47, which in turn is pivotally connected to the inner end of a lever 48,- fulcrumed upon a pin-49 which passes through lugs or cars 50, extending upwardly from the member 4 of the frame or housing, see Fig. 1. The upper end of the 5 link 46 passes between the inner ends of a pair of links 51, said ends being pivotally secured to said link 46 and to a locking block 52, by a pin 53. The outer ends'of 'the'lin ks are fulcruined upon a pin or shaft '54. A 30 link 55 is likewise connected to the locking" block 52. Said block, as will be seen upon reference to Fig. 14, is provided upon itsfvertical face with a series of teeth which are complemental in shape to the teeth formed 5 about the vertically-disposed face 'of the clutch-drum 37. The block is alsd provided on one side at the upper end with a beveled face 56, the purpose of which'will presently appear.

Asabove stated, the clutch drum is provided with an upwardly-extending hub 38," and a set arm 58, shown in detail in Fig. 6, is swiveled o'r ournaled upon the hub, the set arm being held in proper workingrelation with the other members by a cap plate'59 which is attached by bolts or screws to the 1 upper end of the hub 38. Secured to the'set arm and overlying the upper face of the"- clutch-drum is an index-plate or die-160, graduated in inches and fractions thereof, the zero-point being coincident with the de pending face 61 shown in Fig. 6.

The upper face of the clutch drum is pro'-' vided with a spiral groove, as shown in Fig. 1

' 5, which is graduated to indicate the total extent of movement of the knees towardthe' saw, and a pointer or indicator, shown in de-" tail in Fig. 8, works in conjunction with'the spiral. Said indicator is provided with a point or marker 62, with a downwardly-projecting lug 63 which normally rests in the spiral groove, and a dovetail arm or body portion 64, which works in a correspondingly shaped guideway 65 formed in the forward face of the set arm. Said arm is likewise provided with an outwardly projecting nose 66, the under face of which is beveled, as shown in Fig. 6, so that when the set arm is rotated said beveled portion will come in contact with the beveled face 56 of the lock ing block 52 and force the same downwardly so as to bring the teeth'of theblock into con-' tact with the teeth of the clutch-drum and thus arrest the rotation of the drum.

By reason of the downward movement of the block 52, it will be readily "appreciated that the yoke or frame 44 will likewise be 2 moved downwardly through the link connections heretofore described, and as a conse-"1 quence the clutch shoes 36 will be withdrawn from contact with the inner face of the clutch-drum and all further rotation of said drum will be prevented.

In order to lock the set arm to the drum and to cause the same to rotate therewith, and as a consequence impart a rotary motion to the shaft 16 and set-shaft 33, a locking block 67, shown in detail in Fig. 13, is employed. This block is provided with teeth complemental in shape to the bevel formed upon the outer face of the clutch-drum and is held in position upon the set arm by links 68 and 69, the latter being provided with an upwardlyextending handle 70, by which the block may be thrown into and out of locking relation with the clutch-drum.

In use the operator will release the block 67 and swing the set arm 58 around to such position as will give the knees the desired forward movement. In Fig. 9 the set to be effected is 2 inches. A pointer or indexfinger 71 extends outwardly in line with the face 72 of the frame or casting against which the face 61 contacts when the movement of the set arm is to be arrested.

A block 78 is pivotally connected at 74 to one end of the yoke or frame 44, and a link 75 is in turn pivotally connected to said block. The lower end of the link is attached to an elbow lever 76, see Fig. 12, fulcrumed upon a stud or hearing 7 6 extending out- 'wardlv from the frame of the machine, see

Fig. 2. The lever 76 is provided with a round seat or recess 77 and with a curved face 78, to one side of said seat or recess. A foot lever 79 is fulcrumed upon a pin or shaft 80, extending outwardly from the frame of the machine, and to the short end of the lever is connected a link 81, which in turn is pivotally connected to a block 82, Fig. 11. Said block is pivoted to the outer end of an elbow-lever 83, Fig. 1.5, fulcrumed at 84. A link 85 is connected at one end to the short arm of said elbow-lever and at its opposite end to a swinging box 86, which carries a friction driving pulley 87 mounted upon a shaft 88, to which is secured the sheave 6. A roller 92 is mounted upon the lever 7 9, and under normal conditions rests within the curved seat or recess 77, see full lines in Fig. 12. The driving pulley 87 is designed to coact with a driving wheel 89, mounted upon. a shaft 90 (see 3), carrying at its inner end a bevel pinion 91, which intermeshes with the gear 31 secured to the lower end of shaft 16. These parts are employed for receding the knees, and the pulle 87 normally stands out of contact with the wheel 89.

The operation of the apparatus is as follows: Constant motion being imparted to the rope 5, the sheaves 6 and 7 will be rotated in the direction indicated by the arrow in Fig. 1. With the set arm in the position shown in Fig. 9, and it being desired to move the knees to the saw, say, 2% inches, the operator will, through the manipulation of the handle 70, carry the set arm 58 around to the position shown in Fig. 9, when the mark for 2, inches upon the dial 60 will. come opposite the pointer 71. The operator will then throw the handle to the upright position shown in Fig. 2, whereby the block 67 will be moved inwardly and into contact with the teeth upon the clutch drum. The drum will remain stationary until such time as the shoes are moved outwardly into contact with the inner face of the drum, and this is effected through the manipulation of the handle or lever 48. A downward movement of the outer end of the handle will elevate the link 46 and consequently raise the block 52 out of locking contact with the teeth of the clutch-drum, at the same time lifting the yoke or frame 44 which swings about the pivotal connection 74 of the block 73. As a consequence, the sleeve 40 will be elevated and the links brought to a horizontal position, with the shoes or clutch-members 36 in locking engagement with the inner face of the clutch-drinn. The motion of the constantly-rotating quill will thus be imparted to the clutch-drum (b f reason of the fact that the clutch shoes or members are carried by the head of the quill) and the clutchdrum, with the set arm which has been locked thereto, will rotate until such time as the nose or projection 66, carried by the arm, rides over the bevel face 56 of the lockinghlock 52, whereupon the block will be depressed and the teeth thereof will come into contact with the teeth of the clutch-drum. At the same time, through the downward movement of the link 46, the yoke or frame 44 will be depressed and the clutch shoes will be drawn out of working relation with the inner face of the drum. Thus it will be seen that the parts cannot overthrow, and that immediately the setting arm reaches its limit of movement its motion is automatically arrested, and this without shock or jar to the parts. Again, the movement will not be arrested (notwithstanding an; slipping of the clutch members) until the set arm has traveled the full distance and the face 61 comes into contact with the face 72, at which time the locking block 52 will have been fully lowered and the shoes 36 withdrawn from working contact with the inner face of the clutchdrum. tion, which is shown in Fig. 4, the operator throws the handle 70 downward thereby releasing the block 67 from contest with the clutch-dru1n, and swings the set arm around to position to give the neXt required set. so doing, the indicator will be moved in the spiral slot formed in the upper face of the clutch-drum, and inasmuch as the clutch drum remains stationary at this time the indicator will, of course, be moved outwardl Vhen the parts come to this posiblocks'52 and 67 be withdrawn from contact with the clutch-drum, and this is effected by the operation of the foot lever 79 and the parts which work in conjunction therewith. A downward movement of the foot lever from the'position shown in full lines in Fig. 1 2 to the dotted line position in said figure and in Figs. 10 and 11 will first, through the roller 92 and the elbow-lever 76 draw the link downward and as a consequence swing the yoke or frame 44 until the collar 41 comes in contact with the upper end of the box or housing 21, see Fig. 10, whereupon the fur ther downward movement of the lever will 'cause the yoke or frame 44 to rock so as to carry the link 46 upwardly and throw the block 52 out of locking relation with the clutch-drum. As the roller 92 passes out of the seat or recess 77 it will come in contact with thecurved face 78 of the elbow-lever 76, which face is at such time concentric with the fulcrum 80 of the lever 79, and as the roller is moved downwardly to a slight extent along said face 78 the swinging box 86 will be drawn upward so as to carry the friction driving pulley 87 into contact with the wheel or drum 89, whereupon a reverse motion of the parts will be given through the shaft 88,

the'sheave 6 and the connections heretofore 2, ready to be again operated to cause a step-' by-step advancement of the knees in'the manner above set forth.
